To all whom it may concern Be it known that I, J AMES W. SN license, acitizen of the United States, and'a resident of Adrian, in the county ofLenawee and State of ldichigan, have invented a new .RDilTIhPX'OVQtlFence-Machine, of which the following is a specification.

Tlh'isinvention relates to a machine especi llfv designed for producingornamental fabric adapted for lawn and garden fencing, and as objectisto provide simple and etficient means for rapidly and perfectlyproiduoi'n'g, ornamental. fencing wherein pro v sion is made forautomatically feeding the" woof or picket strands into the machine .atpredetermined intervals, and for securgging the pieketstrands to'thelongitudinal or warp strands which may be twisted together on oppositesides of the picket for wootstrands alternately in opposite direc.tions, i The invention further contemplates the storming o'tthe picketor woof strands into '1. arches at. an edge of the fabric, the free endsof which woof strands are secured to .tlie'warp strands. This inventionconsists, in the combination of adrum built up of a series of toothedwheels-to receive the warp and woof Wires, Rand-.ol" a Wheel concentricwith the others 'havingl substantially triangular anvils, 11163118 tomove sait. anvils into position to receive "the wool. wires, means tobend the wool wires around said anvils so asto form it arches, incanstofeed thewarps to the drum and to secure the woot' wires to said warpwires, andfeeding means for positioning the wool wires so that they maybe bent to Form arches and then secured in position. 1 It furtherconsists in means to twist the warp wires to secure the woof wires.

In the aecoinpanyinr: drawings Figured is a plan. Fig. is a front ole'ation and Fig. ,3 is a left side elevation of a machine cinl'ioi'lyingrmy invention. Fig. 4 is a side clevatio'ii of the 'woot or picket strandfeeding, crimping: and cutting; mechanism. Fig. 5 is 1.11 plan of theseine.

Simi ar reference characters refer to like .parts throughout the severalviews.

The machine shown in the drawings is made up of' side frames 1 and 2 onwhich is mounted a short driving shaft 3 in the bear- 10, ings 4, inthe-upper ends of the pedestals 5, .which pedestals. rest on theside'frame 1 of the machine. 4 On this shaftare the tight 1 I pulley 6,the loose pulley 7, and the pinion 8 which meshes with the la e gear 9onthe shaft 10. This shaft 10 is mounted in bearings 12'on the sideframe 1 and carries the mutilatedgear 13, more clearly shownlin Fig.27,;which meshes with the companion gear 14 on the shaft 15, and causesthis shaft to make one half revolution at each alter natehalf-revolution of theshaft 10, and to rest between suchalternate-half-revolutions; The shaft 10 also carries the miter gear 16whichuneshes with .the miter gear 17 on the cross shaft 18. The shaft 15is mounted in bearings 11 on the frame 1.

Asshown in Figs. 27, 28 and 29 the gear 13 has a segmental flange 13which the concave ends of the stop-plate 14 on the gear 14 uring'onehalf-revolution of the shaft. 10, andprevents the gear. 14 from turning.During the other half-revolution of the shaft 10, the teeth of thegear13 en gage one or the other group of teeth'of the gear 14 and turnthe shaft 15one'half-revo.- lution. The beginning and end. of one ofthese half-revolutions are shown in Figs. 27

and 29. res ectively.

The s'ha t 15 is connected to mechanism for twisting the warp wiresemployed to form the fabric, and as these wires are twisted-in alternatedirections bet-wwn .succeeding' pickets, the; parts-are desi ned sothatv for one half-revolution of the s aft 15 the twisting will be inone direction, and for the next half-revolution of the shaft, the,twisting will be in the opposite direction.

During the time occupied by this twisting and the rest following thetwisting, the shaft- 5 0-18 makes one revolution which represents a fullcycle of the machine,'that is, all the op-.

\erations necessary to place and secure one picket between the warpvwires of the fabric. The distance betwcen'the pickets will depend uponthe speed at whic 1 the warp wires are moved, and gearing is thereforepro-. vided for changing the speed of these warp wires. 1

On the shaft 15 are mounted the gears 19,

20 and'21, which may be of any desired construction and which mayconnect to the gears 22, 23 and 24 on the shaft25 in any desired manner.In the present case, these gears are shown to be chain-wheels which 55connect by means of a chain 26. This shaft engages bf each and then inthe other, alternating between 25 is mounted in bearings 27 on the frame1 and carries a worm 28 at its front end which meshes with theworm-wheel 29 on the transverse drum-shaft 30 at the front end of themachine. This shaft 30 is mounted in bearing 33 on the side frames 1 and2 and has secured to it the wheels 32 which receive 32 may the warpwires 34. Each wheel have proper teeth 35, as shown in Figs. 23 and 24,between which the pickets 36 extend secured between the wires of thewarp strands 34. It will be noticed that each of these warp strand; isformed of two wires which rest on the faces of these wheels 32. Thespiders and rims of these wheels arosecured directly to the shaft 30.See Figs. .22 and 23. To provide for the alinement of the teeth 35, ifdesired, in order .to easily providestraight trougl'ls to receive thepicket wires 36, the teeth are preferably independent of the wheels,being formed on rings 37 having slots38, through which the desiredposition. The front ends of the side frames 1 and 2 may be connected'bymeans of the cross frame 31.

Extending across to sideand secured to the frames 1 and 2,

is a frame 40 to which are secured a series of twister heads, 'shown' inFigs. 10 and 13. Each head consists of a body 41 secured at and forminga Each spindlehas a gear 44 at its rear end and is held in position bymeans of plates 45 and screws 46; Each spindle has longitudinal holes 47through which the warp wires 34 can-pass, and-at their rear .ends thespindles may be reinforced by means of hardened sleeves 48. Each spindleis provided with a transverse slot 49 through whichfthe picket wires36are introduced. The pull on the warp wires 34 is from the right inFig.13 50 0f the spindle toward each ,other.-- To prevent this, the plates45am provided with screws 39' extend to hold the rings 37 in any themachine from side the desired position by means of screws 42, bearingfor the spindle 43.

circular collars 51 which engage in circular grooves formed near, thefront ends of these spindles. These spindles twist the'two wires warpstrand, first. in one direction successive pickets, and always resumepositions'pf rest-with the slots. 49 horizontal to permit theintroduction of the pickets. The

mechanism for the turning of thespindles is a followsrSlidablelongitudinally of the frame 40 andtransversely of the machine is arack-bar 54, as shown in Figs. l0and 13,.

'A plate 53' may besecured to therear side of this rack-bar to reventrearward mpvement of the spind es Referring'now; to Fig. 1, itwill beseen'that this rack-basis rovided with a pin 554:0 which it connect,

mg rod 56 is coupled. This rod also couples to a crank pin 57 carriedbythe crank disk 58 whichisinounted iin the shaft 15. The

details of, this construction are more clearly ilhijjstrated .in Figs. 8and 9. It will be seen thatfthe number of rotationsof the spindles.

depends upon the length of movement of this rack-bar 54. In order topermit a variation in the number of twists of the warp wires,the disk.58 may be provided withiadcl-itional.holes 59rd receive the crank pin57,which holes are at different d stances from' the center of the crankdisk. By these mic ans the stroke of the rack-bar 54 may be accurately.controlled and varied according to circumstances.

As shown 1n F1 26, the fabrlc 18 formed of the wool? orpic ct wires 36and the War :wires 34-. This presentmachine is designe near thesame sizeas the wheels 32 and proyided with a series of radlally movable anvils 77, substantially triangular in shape, as shown in Figs. 14, 15 and 80.Mounted on the this shaft 18, the yoke (38 and the arm Go r belmovedforward and swing the arm 7 on frame 2 is a bracket 63 which carries arevoljubleshatt 64 to which 1s secured anarm G5, on the outer end ofwhich 1s a pin 66 which also extends through the outer end i f a lii'ik67. See Figs. 14, 15, 16 and 17.

This link connects adjustably to a yoke 68 which'has a slot 69 throughwhich the shaft 18 en" ids and'by which the yoke is supported. Securedto the shaft 18 is a cam 70 having agroove 71 into which a pin 73 ontl'le'yoke 68 extends.- At each revolution of will the shaft" 64 fromthe position shown in Fig.

to that shown in Fig. 14..

' The picket wires 36 are :t'edin t ansversely to thcrnaehine andlongitudinally of the (lll'ltlILSllilifland assume a position indicatedbythej dotted lines'tl in Fig. 15. The preceding picket l3 is still.straight, while the picket A preceding it has already been bent toanangle of about thirty degrees by its "contact with the shaft 64. Atthe next cycle of "the 1na(.-.hine, the anvil-marrying drum turns thedistance between the wires A and B, while at the same time the arm 74-swings to the position shown in Fig. i l, and a special. device movesthepicketgt from the position indicated in Fig. 15' tothat of F 1g.

As wiilbe noticed in Fig.

14, the picket wires are below the plane of the arm 74. This arm is)IOVltlBd with a downwardly turned linger Hi, secured on a rod 75-011which is a spring 7 5 which normally holds the finger 74: vertical, butwill permit the finger to swing up when the arm Tet passes from theposition of Fig. l t to that of Fig. 15, the linger swinging up to passthe picket C. This finger may have a notch 76 (Ilg. 17) to prevent thepicket wires from bending up or down. are moved laterally into position,it is nec-,

essary that the anvils 77 around which they are bent shall not be. inthe path of these wires until such anvils are necessary, that is, untilafter the wire is moved from the posi' tion (1 in Fig. 15 to that inFig. 14-. Each anvil 77 is mounted on a radial stem 78 passing throughthe ring 79 and the openings 80 of the face of the anvil-carrier (31,and having springs 82 between the ring 80 and the cam-shoe 83 on eachstem 7 A stationary segmental cam 84 is mounted on the frame 40 andconnected to the side frame 2 by means of brackets 85. As the anvilcarrier revolves, the camshoesT 83 engage the outer end of this cam 84and moveinwm'd, as shown in Fig. 19, sliding along this cam until theupper end reached, when the springs 82 will force the anvils upwardly.

.As the pickets The canrshoes 83 en a c the rim of the carrier andprevent the anvils from moving out toofar. As tins anvil carrier isoperated by the "cars 13 andl l as before described, the fabric will bestationary one half of the time and be in motion one half the time...Similarly, the twister heads will be stationary for one half the timeand revolve during the other half of the time. The parts are so timedthat the twisting of the warp wires I will occur during the tune thatthe anvil car-J rying drum is turning, and the twisting will becompletedat the time the anvil carrier ceases to turn, both being driven by theshaft 15. The swinging of the arm 7 4 will be completed just after theanvil carrier has stopped turning, and this arm 74 will remain in. theposition shown in Fig. 14.- until the new woof wire has been placed inposition and the twisting has begun. The mechtllllSlll for laterallymoving the pickets will move with the anvil carrier during such adistance as is necessary to hold the picket (l and the end of the arch Ain position until the warp wire hasheen twisted sulli'.

ciently to lockthcm. After the anvil carl'lQI has made a poi-tumor itspart-revolution, and alter the arm 74. has swung through about one halfof the distanrenactwecu the positions shown in lfigs. l5 and ll, thenext succeeding anvil escapes from the "am S-t and is forced outward byits spring 82, so that it will'be in position to assist in forming thenext succeeding arch when the arm 74' has been swungnnvhrd at it nextoperation.

As shown in Fig. 26, the pickets 36 are crnnped to insure a more ositiveengagement between-them and "t e warp wiresl The mechanism for crimping,cutting and feeding these woof wires is-illustrated in"- Figs. 1, 2', 4,5,6, 7, 32, 33 and-34. The shaft 18 is provided with amutilated gear 86(Fig. 16) which meshes with the pin-- ion 87 on the driving shaft 88 ofthe cutting off mechanism, mounted. in the bearings 89 on the frame. 2..'-This shaft 88 carries a" main driving pinion 90 which meshes with thepinion'91 onithe stub shaft 92', as indicatcd in Figs. 2 and 4. Thepinion 91 meshes with a gear 93 mounted on the shaft 94, which shaftcarries. the gear 95 and the crimping wheel 96 on its other end. Thegear 95 meshes with the gear 97 on the shaft 98, which shaft alsocarries a crimpshafts 94 andl98 are revoluble in hearings in the frames100-and 101. Mounted on t e ing gear. 99, which crimping gears are shownone. larger scale m Fig. 32.

which have teeth'102 as shown in Fig. 32.

. These crimping wheels willbe actuated once at each cycle of themachine, that is, at each step of the anvil-carrying drum, and the linkof wire which is fed through these crimping wheels will depend upon thenumber of teeth nponthe gear 85 on the shaft 7 18. To sever this wireatproper intervals,
